December 14,1929. Serial No. 414,067.

My invention relates to a .base ;for.such

machines as time recorders or calculating machines. More partlcularly it relates to the construction and assembly .of the base.

It is the broad object oflmyinvention to simplify the construction and to facilitate the assembly-of the base.

The invention possesses other advantageous features,,some of which with the foregoing will beset :forth at length in the :following description Where I shall outline in full that form of the machine base of my inven- -tion, which I have selected .for illustration in the'drawing accompanying and forming :part of' the present specification. In said drawing I have shown one form of machine base embodying my invention, but it isto be understood that I do :not limit myself to such :form since .the invention, as set forth in the claims, may be embodied in :a plurality of forms.

In said drawing: I

Figure 2 is a plan View of a portion of the machine base.

Figure 3 is a cross section through the base portion shown in Figure 2 along-the line 83.

Figure 4 is a perspective view of a foot suitable for use with the base. I

Figure 5 is a perspective view of a member and a stud utilized in connection With the base.

With such machines as calculating machines, adding machinesor time recorders, it is usual to provide feet formed of a suitable material, as rubber upon the base of, the machine to protect, against damage, surfaces upon which the machine may be positioned.

the base of a machine, usually in such a manner that they covered one of the studs utilized to secure the base to the machine casing proper. When it was desired to examine the machine, the several feet had to be removed from the base before the studs could be getten at to loosen the base from the casing. In accordance with my invention I am enabled to materially simplify the construction of several corners of the base.

thebase and to secure a foot in positionzon a machine'base at thesame time that the base .is-secured :to the IllilClllllBCflSlng.

- .In that form of the-invention Which I have -shown-in the drawing, machine casing 6 :is

fitted for the reception-0f a base .A;p1u rality of circular pads-l1 are provided at the These arelsuitably recessed as at 12 to receive .a foot 13 0f suitable material .sothat a surface upon which the machine is positioned will not be damaged and so that the machine will be cushioned. Such a .foot is preferably formed of a resilient material as rubber to have a contour similar to that shownin Figure 4.

In accordance with my invention, .1 provide means for SGCUIlIlg the foot 13 in posltiontin the recess 12 conjointl-y with the securing of v the machine baseto the casing atthe @point at which the foot is provided." This I have preferably accomplished by utilizing a stud 16 having a threaded portion 17 adapted to engage the ear provided immediately over the pad 11. The stud is also fformedwith a shoulder 18 adapted to engage the ma'chine base and to cooperate with the threaded :portion 17 in drawing the, base into the desired engagement with the casing. A portion- 19 extending between the shoulder 18 and threaded portion 17 cooperates 'with the base and machine casing to secure theiraccurate ,positionlng relatlve to each other.

The securing of the foot 13 is preferably.

accomplished by providing an aperture 20 centrally of the foot and of a-considerable extent as isshown inFigure 4:. Several fins 21radiate from the :aperture and are joined to annular ring 22 forming rthe outer portion of the foot. This manner of forming the foot afi'ords several advantagesamong which is thatthe fins and annular ring cooperate to prevent theflmachine from sliding with respect to a surface on which'the machine is po ,sitioned while the weight of the machine is distributed-.over the surface.

To ensure that the foot, when assembled, does not work loose I provide means for retaining it against release until desired. This is conveniently accomplished by the provision of a'member 26, preferably in the form of a cross formed by arms 27 as is shown in Figure 5, having an aperture 28 adapted to pass the stud 16, the aperture being off center with I respect to the cross. The arms 27 forming the cross engage the several fins 21 and. serve to position the foot 13 eccentrically with respect to the stud so that rotation of the positioned foot cannot occur. The considerable extent of the aperture allows the stud 16 to be passed through it readily and does not necessitate the positioning of the footin a predetermined manner relative to the stud and cross member 26, thus facilitating assembly.

As the stud is drawn into engagement with the threaded portion in the ear 9, the foot is drawn into the recess in the pad'll'and, as the machine base is drawn up to the casing,

Y the cross member 26 secures the foot in position. The footbeing resilient is tensioned slightly by the drawing up of the stud so that the stud is'restrained against accidental rotation by thefriction'al engagement of the cross and the stud. Byproviding the resilient foot accurate machining of the various parts is rendered unnecessary since minor variations are cared for by it. Thus the length of the stud between the head and the shoulder 18 need not be as accurate as would benecessary if the foot were not resilient.

When it is desired to examine the interior of the casing, the stud 16 is withdrawn from engagement with the ear. Simultaneously,

the foot is'released and the base is then readily removed. This construction obviates the several additionalparts and operations pre viously necessary.

1. In combination, a stud'having athreaded portion and another portion forming a shoulder with the threadedportion, a casing having a threaded portion to receive the stud,

' a base adapted to be secured to the casing and having a c rcular recess eccentrlc w th respect to the threaded portion of said casing, a circular foothaving an aperture therein for positioning in the recess in said base, and a cross'member adapted to be positioned eccentrically on said stud to securesaid foot in position, said stud engaging the threaded portion of the casing to secure the foot in position in the recess in said base, the shoulder portion on thestud engaging the base to secure said base to the casing upon engagement of the threaded portion of the stud with the threaded portion of the casing.

2. In combination, a M casing having a threaded opening, a base for positioning on the casing, said base having a circular recess therein eccentric with respect to said opening,

a resilient foot having an aperture therein,

a stud adaptedto be passed through the aperture in the foot, said stud being threaded to engage the casing and having a; shoulder thereon to engage the base to-draw the base and easing together, and means on the stud threaded portion of the stud with for engaging the foot to secure the foot within said recess in thebase conjointly with the base.

4. In a device for securing an apertured resilient foot in a pad on a machine base, the

foot having fins formed therein, a'crossmember adapted to be inserted in the footto engage the fins, the cross member having an aperture offset with respect to the center of the member, and a stud adapted to be passed through the aperture to draw thecrossm'eniher and foot non-rotatably together. 1

' 5.- In a combination,a stud having athread ed portion and another portion forming a shoulder adjacent the threaded portion, a casing having a threaded portion to receive the threaded portion of the stud, a base'ad'apted I to be secured to .the'casing, said base'having a recess therein eccentric with respectto the threaded portion of said casing, a foot having 1 an aperture therein for positioning in the recess in said base, and a cross member adapted tobe positioned on said stud and to engage the foot to secure said foot non-rotatably in position, said stud engaging the threaded portion of the casing to secure the foot in position in the recess in said base, the shoulder portion on the stud engaging the base to secure the base to the casing upon engagement ofthevthe 'threaded portion of the casing.

In testimony whereof, I have hereunto set my hand. V V
